If he could only offer an apprenticeship as a living deshi like the one experienced, I'd be on my flight already! Unfortunately, coming to Japan as a lonely loner + having to pay for rent and food in an unpaid apprenticeship is impossible without any big funds. Five years without payment though are in my opinion, nothing for what you will get in return. Knowledge, independence, confidence in yourself and much more. It will be very hard yeah, but you've got to fully commit. I don't understand the upset folks. Today we all have to make the quick $$$ as early as possible, don't we?
